Thanks for the heads up... will keep that in mind.
So I used it today... all works very well!
The thing that gets me though is this...
... but the soot level was only at 14%. With not a lot of driving (went to the shops twice, which involves highway run and 80km zones) and it's jumped up to about 40%. I noticed that that the soot level rose VERY quickly when cruising with the RPM's at around 2400-2600rpm (approx 1% every 10 seconds), drop that down to lower revs (1800-2000) and it was a much slower rise. This goes against EVERYTHING that I've been reading about these subie diesels... ie... keep the revs up a bit, drive them harder, etc.
This tallies exactly with how my car behaves. The soot level registered seems to increase with temperature. Twice I've seen once I stop the engine during a regen at ~30% soot, a cold (next morning) restart will register 0% soot. It can then be 10-14% by the end of the street, and increase at 1% per 2 seconds thereafter up to ~30-33%.
After that, it wobbles about a bit but gradually increases to the regen levels. Usually gets stuck in the 40-60% range, cold restarts result in some reduction but not much.
An uphill run during a regen drives it down quite quickly.
I suppose at least this way it's a sort of 'failsafe', i.e. when at working temp it's more likely to trip a regen rather than have it decrease the value when hot. As it gets really hot when regenning, I suppose this encourages a full burn-off as the soot value will also reduce with the reducing temp after the regen.
The other issue is the boost level... I had that logged on the trip home and it didn't seem to get over 7lb (I probably revved it up to about 4000rpm)... I thought these engines pushed a lot more air than that?
My too, exact same reading.
I'll be removing the EGR valve in the morning and giving it a proper clean... will be interesting to see how mucked up it is... will also try lubing the cog that the motor drives and see if that helps with anything. I'll take some pics and put it into a post when I do it.
Hmm, given what you've written elsewhere and the boost level afterwards, I think I'll be looking at things...
